Fascinating snakes

Herpetophobia is the morbid fear of snakes. While they may provoke phobia in some, snakes are amazing animals with some pretty striking (please pardon the pun) attributes. Check out the list of some of them below. And for a closer look at the more common snake species in our area (yes, live specimens will be there for the viewing), attend the next week’s Walk in the Woods Nature Lecture.

Where you’ll find them…

Snakes can live in almost any environment, ranging from jungles and deserts to lakes and mountains. They live everywhere on Earth except Ireland, Iceland, New Zealand, and the North and South Poles.

There is an island in Brazil known as the Snake Island that arguably has the highest occurrence of snakes in the world. It’s estimated that there is one snake every 11 square feet.

The most common snake in North America is the garter snake.

They come in all sizes…

The smallest snake is the thread snake that lives on the island of Barbados. It is about 4 inches long and “thin as spaghetti.” The longest snake is the reticulated python which can reach over 33 feet long. And the heaviest snake in the world is the anaconda, weighing over 595 pounds.

Eating habits…

All snakes are strictly carnivorous. Depending on their size, however, their prey differs considerably. The smallest snakes feed on insects, snails, and mice while the largest snakes kill and eat anything from an antelope, pig and even a jaguar.

Most snakes need to eat only six to 30 meals a year to stay healthy.

To keep from choking on large prey, a snake will push the end of its trachea, or windpipe, out of its mouth, similar to the way a snorkel works.

Snakes don’t lap up water like mammals do. Instead, they dunk their snouts underwater and use their throats to pump in water.

Some snakes have over 200 teeth. The teeth aren’t used to chew—they point backwards to prevent prey from escaping the snake’s throat. And only venomous snakes have fangs.

Snake biology…

Most species of snakes lay eggs, and some species are ovoviviparous (they retain the eggs within their bodies until they are ready to hatch), but it was recently found out, that several species (such as the boa constrictor and the green anaconda) are fully viviparous (giving live births).

Snakes are completely covered with scales—even their eyes. Instead of eyelids, they have a brille, which is a transparent, disc-shaped, immobile scale that covers the eye for protection.

While snakes don’t have external ears, or eardrums, their skin, muscles and bones carry sound vibrations to the inner ears.

To accommodate their narrow bodies, snakes’ paired organs (such as kidneys) appear one in front of the other, instead of side by side.

Pit vipers, pythons, and some boas have infrared-sensitive receptors in deep grooves on the snout, which allows them to “see” the radiated heat of warm-blooded prey.

Snakes have one of the highest occurrences of polycephaly—a rare condition of having more than one head. There have been many cases of two-headed snakes. The heads might fight each other for food.

Species with super-powers…

The brahminy blind snake is the only snake species made up of solely females. It’s also the most widespread terrestrial snake in the world.

The death adder has the fastest strike of any snake in the world. It can attack, inject venom, and return to striking position in under 0.15 seconds.

There is a genus commonly known as the flying (or gliding) snakes. Native to Southeast Asia, these snakes are capable of gliding over distances as great as 330 feet through the air. Watch the video below to see how they do it.

The muscles that cause a rattlesnake´s rattle to shake are some of the fastest known, firing 50 times per second on average, sustained for up to 3 hours.

The black mamba is the world’s fastest snake. It’s found in East Africa and can reach speed up to 12 miles per hour.
